To'alluikmri it ma concern:

Be it known that I-,-

at Detroit, in the county of Wayne and State of Michigan, have invented a new and'lm T proved Truck-BodyQTilting Mechanism; --o'f-;

which the following is a specification,

It is customary to use a hydraulichoistj the associated mechanism for dumpingth'e turer whereasthe chassis and power plants of the trucks onwhich they are installed are built by various 'othenmanufaoturersand in widely different designs. The present in-.

yention relates to means whereby the hoisting mechanism may be driven from a" driven shaft ofthe truck, said means being-of a nature such as to allow substantially the entire hoisting means to be made standard reardless ofordinary-variations in'the' size,

' -shaft and a pump drivin therefrom longitudinally o the vehicle and out of alinement therewith, shafting for so pe and location of'theparts of thejdiflerent chassis and powerplants. 4

To this-end the invention comprises, in combination with a transmission countergear removed driving'the gea'r'from the countershaft, said shaftingbeing so constructed and arranged as to allow relativeuniversal movementat. whereby'deflec.-

two points along its length tion due to loads on the. oisting mechanism is freely allowed. The iiivention also y consists in drivingmeans of the nature just described 'wherem .a portion at least of the shafting is bodily movable toward and from fthe countershaft to make or break thefdriv ing connection; also in clutch shafting com-f relievin the parts of'friction whenthe'y are out of riving relation, The invention fur- -ther consists in" certain details of construction shown, described and claimed.

The present invention is an improvement on the construction disclosed and claimedin ,my a plicationfo'r patent Serial lflumbei' 14240 filed January 15, 1917 In the drawings, Figure 1 is aside view,

spective views-oftheend of the counter- I shaft, the .clutch member attached thereto made. Fig. 9 is a fragmentary view shows andthe" .bolt whereby theattachment is the rear-wheels, and 3 the hopper body I mounted to tilt aboutthe pivots 4 when a piston" rod. (not shown) 'is projected l p-- wardlyin the cylinder 5. This general cons'truction is well known. In this instance,

however, one of the cross bars 6 uponwhich the base 8 of the cylinder rests'is' preferably f arrangedto receive the front ends of'the side bars 9 of the body, it"being' understood that the latter includes the cross beams 10' Ion which the hopper directly rests. The

body also preferably-includes] body arms I formed of angle or channel irons, the upper portions'1f2 ofvwhich are securedto the front .en'd of thehopper and the lower-portions 13 of whichiarebent forwardly to receive the shackles'15 of the cables'jlfi that pass over "thejp lYsls carried by the piston rod,'-.the other ena's'gpfjthe. pulleys being preferably anchoredito {the front cross bar 6 7 near the outer ends thereof. The truck is driven in any desiredw'ay, preferably by means of the usu'al engine-20; transmission or gear, box 21 andpropellershaft 22, connected to a main driving shaft 23lbya-universa1 joint 24.

-' Depending from the. front cross bar is-a YSIIPPOI't 25, preferably an"-angle iron, upon which a gearpump,26,'that drawsoil from the upper portion of the. cylinder through the suction pipe 28 and delivers 'it'to the base thereof through the pressure pipe 29, is mounted; Also mounted in a bearing 30 (Figs. 2,3 and 4s) onthe side of the support opposi-te the pump is a rotatable member 32 proper axial alinement therewith.

Projecting rearwardly from the gear box is a counter shaft 40 having its end 41 substantially rectangular in cross-section and tapped at 42 to receive the threaded end of a screw bolt 43, whereby a clutch member 44 (having a socket 45 conforming to the end 41) may be held firmly against the shoulder 46 on the countershaft and therefore in A look washer is preferably interposed between. the head of the bolt and the end of the clutch member. It will be observed that the latter includes a substantially spherical-portion 49 from which the alined studs or clutch teeth 50 project. The member 43 might be made integral with the shaft 40.

The shaft member 35 is provided with the spherical head 52 having a transverse slot 53, the shape of which may vary considerably; as shown, it is wider longitudinally of the shaft than transversely thereof and tapers inwardly to the center from both sides. Projecting through the slot is a pin 55, the ends of which also pass through the walls of a clutch tube 56 whose opposite end is slotted at points substantially 180 apart and preferably through arcs of substantially 90 as indicated at 58 to form jaws 59 between wliich the'studs or teeth 50 are received. The slots, being of much greater width than the teeth, it follows that the latter are readily engaged with the jaws when the clutch tube is thrust forwardly. The walls of the slots are preferably left overhanging at 60, which tends to retain'the clutch members in engagement with each other. g

It will be understood that the countershaft may turn continuously. In order to relieve the clutch parts of friction as well as tohold the clutch tube in proper position to engage the clutch member 44, .the bolt 43 is continued at 62 to form a bearing for a roller 63 upon which the weight of the end of the clutch tube is carried when the clutch members are out of engagement. When the parts are in driving relation the tube rests on the spherical portion 49 of the member over which the end of the part 62 is riveted.

In practice the countershaft is seldom, if

all parts, with the exception of the tube 56,

, member 72 having a circumferential groove or key 96..

ever, alined with the, gear 3Q-33, the amount which one is offset in respect to the other, as well as the distance between them, varying considerably in the different makes of trucks. With this construction, however,

may be made standard, and the tube may be shipped in extra length and cut off and perforated tov receive-the pin 55 in accordance with the particular job. A wooden plug 69 may be driven into the tube 56' to retain lubricant for the roller 63. Instead of makingv the member 56 of a tube, the central portion might be solid as is obvious. By this construction deflection of the hoisting mechanism as the heavy loads are received thereon is freel allowed; the shaft 40 may also be located 0 ose to the propeller shaft (as'shownit is just below the latter), thus enablingthe use of a gear box of mini- V mum size and interfering to the least possible extent with the various mechanisms usually found in this region, as wellas allowing clearance for the fluctuations of the j propeller shaft. 1 90 Various means may be employed for shifting the shafting towardand from' the gear box'. A shown, the pins 38 are tapered at 70 and received in an annular spool-like 95 73 inwhich are receivedshoes 74 pivotally mounted in the ends 7 5 of a yoke member? 6 by means of threaded pins 78 '(Fig. 3). Nuts 79 hold the member 72 tightly against the'flange 36.- ,The other end 80 (Figs. 4 and l0) of the member 76 is received in a socket 81-formed in the pump, and a lever 82 (pivoted on a stud bolt 83 and having a a divided end 84 that fits into a groove 85 of the yoke member) together with a link 86. 2) constitutes means for swinging the member 76 aboiit a vertical axis. The pins 38 may have heads 87 that engage with the member 32 to limit the movement in one direction. The-pump is driven from the 110 gear 33 by means of a chain 88 and gear 89 It is evident that many changes may be made .in the construction of the several parts. In Fig. 11,the member 35 is replaced by a two-part member, one part 90 of which 116 has a rib 91 and a flange 92 corresponding to the rib 39 and flange 36 heretofore described. The part 90 is hollow and receives the shaft 93 upon whicha head 94 of the same construction as the head 52 is formed. 120 Compensation for the differences in alinement and position of the various major parts may be secured by cutting off the shaft 93 to the proper length on the job and there after tapping partly in said shaft and partly 126 in-the element 90 to receive a locking screw In accordance with the patent statutes, 1 have shown and described what I regard as the most desirable embodiment of my inven- 1'3 0 4 tion, but, as stated above, the actual details are subject to muchvariation, I do not,
